Discount supermarkets Aldi and Lidl are feeling the benefit as inflation causes the price of household staples to rise in supermarkets.

Research shows that grocery inflation is up 2.3% versus the same time last year, with products such as butter, fish, tea and skincare all seeing price hikes.

Rising prices will cost the average household an additional £21.31 at the tills, the group said.

Fraser McKevitt, head of retail and consumer insight at Kantar, which carried out the research, said: "We expect inflation to continue to accelerate, and as a result we're likely to see consumers looking for cheaper alternatives."

He added that sales of supermarkets' own label products and discounters such as Aldi and Lidl stand to benefit.

The German duo both hit record high market shares over the past 12 weeks, and now have a collective 11.7% share of the market.

Aldi's market share rose from 6% to 6.8% in the 12 weeks to March 26, and Lidl saw its share grow from 4.4% to 4.9%, according to Kantar.
